This is exactly why I got a NIB Inferno (Original), Uranium, and Uranium Pearl sitting in my collection....excellent coverstock!
Snap! I have loads of Activator NIBs; Original Inferno x 2, Absolute Inferno, Vapor Zone, Red Zone, PBA Inferno (Activator Max), Uranium Pearl, Dirty Bomb and Awesome Flip.
I still use my Zone Classic, Ultimate and Red Zone in league and tournaments (though I don’t bowl many tournaments these days), and I’m planning to use my Vapor / Absolute again in league soon.
RE: Red Zone, mine has had the polish taken off so it’s basically an Ultimate Inferno with asymmetric core, but with 2000-grit rather than 800.
Of the lot, I think the Zone Classic is my favourite. Wish I had bought another one or two NIBs then.
But yeah, Activator can’t do no wrong!
RE: Inferno line, the one ball that I didn’t like was the Total Inferno. Guess what? Not Activator cover!
